A true 'transparent' background is useless IF whatever you put on the
lowest level is really the background or bottom layer. What you
probably really want are one or more semi-transparent layers higher
(positioned above) your background layer. These depending on their
alpha setting will allow some of the lower or a background layer to
bleed through.

For example if you have a image on your "background" layer and then
creae new layer and draw a object, lets say a orange colored square,
and then make it a symbol then change ITS alpha to 50%, if you positon
this orange square over the background image you'll have the
underlying image take on a orangish cast since the square in 50%
transparent allowing the image blow to bleed through.

Changing the alpha can be done manually (right click on the symbol) or
with ActionScripting.

__ALL__ SWF movies always have transparent backgrounds.

It is Flash Player that will display a solid background behind your SWF file
(in the color your HTML or SWF file nominates).

You can tell Flash Player to NOT display a background behind the movie .. by
setting wmode to "transparent" in the HTML object and embed tags.

HOWEVER .. transparent wmode is VERY buggy .. it can make movies play upside
down, not scroll, stop buttons from working, movie content being offset etc
etc. Also it does not work on all browsers.

So effectively the answer is you CANNOT have a non-trivial SWF with a
transparent background in a browser (without it stuffing up the movie).

You can, however, make third-party projector EXE's (eg SWiSHstudio, Jugglor
, SWF studio etc etc) that have transparent backgrounds and can run on your
desktop over other windows etc.
